Be it known that IVA'. JUsBERG, of Galva, in the county ei Henry, andStateof 1lliuoishavo invented new and useful improvements in Pu1nps; andI do hereby declare that the following is a full, clear, and

exact description thereof, which will enable others skilled in the artto make and use the same, reference being'- had to the accompanyingdrawings, forming part of this specification.

Figure 1 is a transverse vertical section and part 'elevation taken inthe plane of the line :a: fr, fig. 2. Figure 2, a horizontal section,taken in the plane ofthe line y y, iig. 3. Y Figure 3, a verticalsection, taken 'in the plane ofthe line 'e z, iig. 2; `and Figure 4, atransverse vertical section, taken in the plane ofthe line v vpg. 2.Similar letters of reference indicate corresponding parts. I

The im rovements in um s embraced in the resent invention can be a liedto either sin le or double P P P P V PP g action pumps, and theinvention consists- First. In so arranging thc several valves' and thecommunicating" passages, both inlet andoutlet, to thev piston orplunger-cylinder of the pump, that the water or other liquid will bedrawn into the same, both in the downward and upward movement oftheplungcr, so that as it is discharging before the plunger incither'ease, whether moving up or down, it isY receiving behind or backof the plunger, whereby, even with a single plunger, or piston andbarrel, or cylinder, a continuous stream or discharge of water issecured.

Second. In so connecting two or more pump-cylinders, both of which 'areprovided with valves and communicating passages, according to the firstpart of the invention, that only one supply and only one "discharge pipeare required. I

Third. In forming at each end of the pumpcylinder, a. chamber orboxsimilarly so partitioned that the Water will be divided and carried,or allowed to pass, to both ends of the cylinder, if only one is used,and similarly to the other cylinders if two or more are connected.

Fourth. In the combination of' side cylinders to the plunger-cylinder orcylinders of the pump, theone for the passage of water to thepump-cylinders, and the other for the discharge of the water therefrom.

In addition to the above, I have also made other improvements in thedetail construction of the punip in" its various working parts, that forthe successful and eiiicicnt operation of the pump are most important,as willbe obvious from'the description to be 4hereinafter given. 1

A A, inthe drawings, represent two cylinders or` barrels, of similarshape and size. These cylinders .A are placed the one alongside of theother, and by'meansof continuous head-plates B B2 are closed at theirupper and lower ends respectively; the headplates being .held togetherby means of suitable tie-rods or bolts C, extending from one to theother, with nuts screwcdtherein. -Thejoints between the head-plates andcylin ders are sealed with a packing,D, of any suitable kind appliedthereto. At each end of the cylinder A, outside of their-head-plates B152,0. chamber, E, is formed, by mcansof a plate, F, applied thereto,that is hollowed or cut out upon its face toward the cylinderdleads.These chambers Eure partitioned along their length, or in the plane, oraparallel plane between thecentres of thepump-cylinders, so as to formtwo chambers in each, which, for a more perfect comprehension of vthedescription of thc operation of the pump to be hereinafter given, havebeen lettered, in the case of the chambers at the upper and lower endsof the cylinders, respectively, G and G2, nud-.Gr3 and G2. H H2,openings in the lower head-plate B2,to cylinders-A, two to eachcylinder, The openings H communicate into the chamber G, and theopenings H2 with the chamber -G2, each opening being provided with avalve, I, that in the openings I-I are arranged to open into/thepumpcylindcrs, and in thel openings H2 to open into the chamber G2. JJ2, openings in the .upper headplate' B to cylinders A, two to eachcylinder. The openings J communicate with the chamber G3, and theopenings J2 with the chamber G, cach opening being provided with valveK, that in the-openings J are arranged to open into the pump-cylindersA, and in theopenings J2 to open into the chamber G4., L, 'the supplypipe to the-pumpi cylinders. This pipe communicates with the chamber G2,at the lower end of the pump-cylinders. M, the discharge pipe for thewater from the cylinders A. This pipe communicates with the chamber Gr4at the upper end of the cylinders A. N N2, two cylinders or chambers,interposed between the cylinders A, which chambers, at thcir'upper andlower ends, are closed by the head-plates B B2, in common with thecylinders A. The cylinder N, at its lower end, communicates through anopening, 0, with the chamber G?, and at its upper end through an4opening, O2, with the chamber- G. The cylinder Nzcommunicates at itslower end through hole O3 with the chamber G, and at its upper end,through hole O4 with thc chamber G3. P, the plunger or pistonheads forthe cylinders A, one to each cylinder, wherein they are suitably packed,to move air and water-tight. 0, the rods to the plungers P, from whichthey pass out through the head-plate B, and are hung by their upper endsto pitman-rods R2, that by boxes are hung to the cranks S of thehorizontal shaft U. This shaft U turns in bearings V of uprightframes-W, and with its gear-wheel X engages the gear-wheel Y of thedriving or operating-shaft Z.

Having thus described in detail the construction and arrangement of theseveral parts, I will now explain their operation or connection witheach other.l n i As the driving-shaft turns, the two pistons P are madeto move up and down within the cylinders A, the one afte'r the other,when, as the one descendsn and the other ascends, the water before themin each case is forced out ofthe cylinders in the first instance,through the valve I, opening outward from such Acylinder into thechamber G, and from thence up through the cylinder NZ into the upperchamber G3, and thence down into the same cylinder upon the other sideof the piston or plunger thereto, and in the other instance, up throughthe valves K of such cylinder opening outward and into the chamber G,and from thence into the discharge pipe M. The pistons having thuscompleted their stroke in the one direction in each ease within thecylinder, by continuing to turn the driving-shaft, the plunger, which inthetirst instance moved downward, now moves upward, and the reverse withthe other plunger, the water in the first lease, above the piston,passing out of the cylinder into the discharge pipe, through the uppervalves K, opening into the chamber G,`at the same time drawing in waterfrom below, through the valves I, suitably opening therefor, while, inthe `other case, the water below the piston is being forced through thevalve below into the chamber G, and from thence up through the cylinderN2 into the chamber G3, and through the valve K, in the same cylinder,down into the same above the piston or plunger. l

From the above description it is plain to be seen that a continuousstream of water is of necessity discharged from the discharge pipe tothe pump. To make the piston-rods water-tight in their movement throughthe heads to the cylinders A, I construct a box packing, A2, around thesame, whereby the water is prevented from working through the same, asthe pistons move up and down.

I claim as new, and desire to secure by Letters Patent- Thearrangement-of the pump-cylinder A, cylinders N N2, chambers G G'z G5G-, valves I K, plates B B2, and F, land forming chambers Efalloperating as described for the purpose specified.

The above specification of my invention signed by. me this dayvof 1867.
